lovekraft Posted August 4, 2005 Report Share Posted August 4, 2005 Not enough info - we'll need some idea of what you've done with those speakers in order to say anything more than, "It must be broke!" Quote Link to comment Share on other sites More sharing options...
Paul Marossy Posted August 4, 2005 Report Share Posted August 4, 2005 it was working when i first wired it but now nothing. Are you sure that you didn't fry your output transformer? You don't happen to have a Marshall amp, do you? Marshalls are notorious for not being tolerant of speaker impedance mistmatches... Quote Link to comment Share on other sites More sharing options...
slayer63636 Posted August 4, 2005 Author Report Share Posted August 4, 2005 i have a home made cab. i copyed the specs and wiring from a crate 4X12 cab. anywho i was testing them to see of the worked and the first one did but when it conneced the other one i got sound. when i conneced both of em up i got nothing from one of them. i was careful and turned the amp off to between adjustment. as far as my amp goes it a little crate amp that pushes 30 watts.

Is your amp tube or solid state? Quote Link to comment Share on other sites More sharing options...
slayer63636 Posted August 4, 2005 Author Report Share Posted August 4, 2005 im sorry for not making it clear. i have a single cab with two 12 inch speakers. as far as my amp it is solid state. i know its the speaker since i tryed to hook it up in a buddies combo amp and still no sound.

lovekraft Posted August 4, 2005 Report Share Posted August 4, 2005 Disconnect the suspect speaker and check it with a multimeter on the lowest resistance setting - if it reads open (infinite ohms) or shorted (less than 2 ohms or so), it's fried. If not, try wiring the pair in series (speaker 1 + lead to amp output hot lead, speaker 1 - lead to speaker 2 + lead, speaker 2 - lead to amp output ground lead). If one works but the other doesn't, the quiet speaker is toast. Quote Link to comment Share on other sites More sharing options...
Paul Marossy Posted August 5, 2005 Report Share Posted August 5, 2005 So, what's the verdict slayer63636? Now that everything is clear to me, I am curious... Quote Link to comment Share on other sites More sharing options...

slayer63636 Posted August 6, 2005 Author Report Share Posted August 6, 2005 the verdic is in. the speaker is blown. i ran it thru the multi meter and it was not getting any resistant. i ran the other one and it was reading at 8 ohms. oh well i only paid 10.50 fo both of em so i really dont care. thanks to all of those who took the time to help me out.
